Hi Brainiac
The difference between Geography and health is that geography is about the earth or the universe but health is about nutrition or food etc..
So this is one of the difference between Geography and health and I hope that's help:)
Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
P waves would arrive first because they are significantly more faster than the S waves.
Well its self explanatory if the climate changed it wouldnt be a rain forest
